PRINTERS QUOIN.

srncrrronmron forming pare of Letters Patent No. 744,806, dated November 24, 1903.

Application led May 6, 1903. Serial No. 155,953. (No modehl To a/J whom t may concern:

Be it known that I, WILLIAM H. ScovILL, a citizen of the United States, residing at the city of Kalamazoo, in the county of Kalamazoo and State of Michigan, have invented certain new and useful Improvements in Printers Quoins, of which the following is a speciiication.

This invention relates to improvements in printers quoins.

The objects of the invcntin are to provide an improved printers quoin which maybe readily adjusted and securely retained in its adjusted position.

. Another object is to provide an improved printers quoin which is simple in its structure and operation and in which the coacting` members are secured together and may be readily adjusted and secured in their adjusted position or released therefrom.

Further objects and objects relating to structural details will appear from the detailed description to follow.

l accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawings, forming a part of this speciiication, in which` Figure l is a side elevation view of a structure embodying the features of my invention. Fig. 2 is a detail longitudinal sectional view taken on a line corresponding to line 2 2 of Fig. 3. Fig. 3 in an end elevation View looking from the left of Fig. l, showing the details of the locking-dog. Fig. 4 is an inverted plan view of the quoin A. Fig. 5 is a similar view of the quoin A.

In the drawings the sectional view is taken looking in the direction of the little arrows at the ends of the section-line, and similar letters of reference refer to similar parts throughout the several views.

Referring to the lettered parts of the drawings, the quoins A A are provided with one flat side and an inclined side substantially the same as the well-known quoins now in general use. Theinclined faces of the quoins are provided with racks or teeth to receive a key by which they are adjusted in use, these racks and the key being of the usual or any desired construction.

Secured to the inner faces of the quoins A A' are bars B B', respectively. The inner faces of the quoins A A are cut away, so that the bars in position form slots d a to receive the loops or plates C, which are secured to the head or large end of each quoin. The members are thus slidably secured together. The bar B is provided with teeth on one of its edges. On the head of the member A is a pivoted dog D, having a projecting lug d', adapted to engage the teeth of the bar B'. With the parts thus arranged the quoins may be adjusted or locked up in the usual manner and retained in the adjusted position by` forcing the dog D into engagement with the teeth on the bar B". The dog D is provided with projecting inturned lugs d at each end, which are adapted to engage the sides of the quoin to limit the movement of the dog and are also convenient for manipulating the dog. It will be noted that the dog can be operated no matter which side of the quoin is up.

The bars B are preferably of brass or some like material which is not likely to corrode from contact with ink or water, so that the members are always readily and easily adjusted upon each other. This maybe done at comparatively light expense, as it will be ob served that but a small amount of material is required. The structure is therefore very economical to produce.

I have illustrated and described my iin-4 proved printers quoin in the form preferred by me on account of its economy of manufacture and durability in use. I amA aware, however, that it is capable of very considerable structural variation without departing from my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. The combination of a pair of quoins A A; a bar B secured to the inclined face of said quoin A; a bar B having teeth on one edge, secured to the inclined face of said quoin A loops (l carried by each of said quoins, engaging the bar on the other 5 a dog D on the quoin A adapted to engage said teeth on the bar B; and projecting lugs d on said dog ICO 'a bar B secured to the inclined face of said quoin A; a bar B having teeth on one edge secured to the inclined face of said qnoin A;

loops C carried by each oi' said quoins en-' gaging the bar on the other; a dog D on the quoin A adapted to engage said teeth on the bar B; all coacting for the purpose specified. 3. The combination of a pair of quoins A A/; bars on their inclined 'faces adapted to slide one upon the other; loops on each of said quoins engaging the bar of the other; teeth on the bar on one of said quoins, and a dog on the other quoin adapted to engage said teeth, for the purpose specified. v

4. The combination of a pair of quoins A A', bars on their inclined faces; loops on each of said quoins engaging the bar on the other;

teeth on the bar on one of said quoins; and a dog on the other quoin adapted to engage said teeth, for the purpose specified.

5. The combination of a pair of quoins A A', bars on their inclined faces adapted to slide one upon the other; and loops on each of said quoins engaging the bar on the other, for the purpose speciiied.

6. The combination of a pair of quoins A A, bars on their inclined facesg'and loops on each of said quoins engaging the bar on the other, for the purpose speciiied.

ln witness whereof I have hereunto set my hand and seal in the presence of two Witnesses.
